FTP server not working

as soon as I upgraded to the DD-WRT today my ftp server was no longer reachable from outside my LAN.. I'm no longer able to reach it from inside my LAN either..DD-WRT didn't change my internal ip addies and the internal ip addy on my ftp' servers box is still the same.. i'm not sure why FTP is no longer working.. does DD-WRT allow incoming ftp connections?//////
